You’ve missed my point.
The lack of specificity in the original question suggests that Black culture is some homogeneous entity, as if to suggest that all Black people are alike in traditions, mode, lifestyle, and outlook. There is an enormous range of culture(s) within the Black community in this country.
The structure of your question oversimplifies Black culture and posits it as a singular quantifiable “thing” to be held up to some sort of scrutiny of it’s quality, which would mean the sum total of the African American diaspora can be critiqued with “It’s good.” or “It’s bad.”
Also, asking about it’s effect on “main(stream) [My addition] society”, only contributes to the overarching problem. It furthers the “us v. them” mentality that continues to cripple this nation, and I don’t use “versus” as solely an indicator of hostility or conflict. Here, I refer to strictly binary thinking.
My point is simply: by asking people to offer opinion on Black Culture, you’re asking them to continue not embracing it as an aspect of their own (American) culture… and perhaps most sinister, you’re inadvertently asking people to offer opinion on Black PEOPLE—as referenced by the above “representative” sample of—- “rude, militant, self righteous’ look at all shit I bought and how rich i am on credit arrogant assholes that I’ve ever met”, prefaced by the requisite disclaimer of knowing that there are “cool” Black people out there, as if to say that kind of behavior is somehow inherent to the culture.
However (I assume) well-intentioned your question may be, I was a little disheartened by the way it was asked.
